ASA GREENVOOD, OF MARLBORO, NEW HAMPSHIRE.

MACHINERY FOR TURNING CLOTHES-PINS.

Specification of Letters Patent No.

T0 all whom t may concern.'

Be it known that I, Asx GREENWOOD, of Marlboro, in the county ofCheshire and State of New Hampshire, have invented a new and usefulMachine for Manufacturing Clothes-Pins; and I do hereby declare that thesame is fully described and represented in the following specificationand accompanying drawing, letters, figures, and references thereof.

Of the said drawings, Figure l, denotes a top view of my said machine.Fig. 2, is a side elevation of it, or a view of that side on which thedriving crank is situated. Fig. 3, is an elevation of the opposite side.Fig. 4, is a central vertical, and longitudinal section of it taken soas to exhibit a front edge f view of the cutters for forming the neckand head of the clothes pin, and separating the pin from the stick fromwhich it may be made. Fig. 5, is a vertical and transverse section ofthe machine the same being taken between the mandrel and cutter forrounding t-he stick, and so as to exhibit the said cutter and variousother parts adjacent thereto. Fig. 6, is a transverse section takenthrough the cutter which forms the body of the clothes pin. l

A, in Figs. l, 2, 3, 4, is the supporting mandrel. It is supported bypuppet heads B, B, and has one or more driving pulleys C, C, fixed uponit. Its front end is provided with a suitable chuck contrivance, orlorifice a, for holding one end of the stick of wood from which theclothes pins are to be successively turned.

D, is a long center rod, whose front end or that next to the mandrel ismade conical or pointed as seen in the drawings. The said center rod hasits axis arranged in a straight line with that of the mandrel and issupported by two posts or standards E, F, and so as to be capable ofbeing slid or freely moved to and fro in a longitudinal direction insuitable bearings made in or applied to the said posts Vwhich extend upfrom a sliding carriage or frame Gr, supported by and so as to slide onparallel rails H, H, and in directions toward and away from the mandrel.rlhe said two rails are made parallel to each other and the axis of themandrel.

Directly over the center rod D, is a long pattern lever I, which playsvertically on a pin or fulcrum b, applied to the top of a post K, whichis arranged and fixed on the 6,935, dated December 11, 1849.

front end of the carriage Gr, as seen in Figs. l, 2, 3, it. A portion ofthe lower side of the said pattern lever, is hollowed out as seen at c,the said part being made to operate in connection with the lower part orbottom of a fork L, which is affixed to the center rod D, and made toextend upward and receive the pattern lever, between its prongs. Thecurve or hollow c, is intended to regulate the movements of the cutteral, or that which performs the o-flice of shaping the body of theclothes pin, or that part of it which extends from e, to f, in Fig. 7,which is a side view of a pin blank, as it comes out of the machines;the part which is afterward removed from it by other means beingexhibited by dotted lines. The said cutter (l, is attached to and heldin position by a slide 2, aflixed to the front end of the pattern leverI. It operates on the upper side of the stick, while the other cuttersLm, or those which shape the neck e, g, and head g, h, Fig. 7 of theclothes pin, operate on the under side of it, they being arranged uponand fixed to a bar n, of a transverse sliding carriage m, as seen inFigs. 1, 3, and 6. The cutter m, is a gouged shaped one, and forms thehead of the pin, while the other l, is properly shaped to give therequired form to the neck g, c. There is also another cutter 0, which isso placed in, or affixed on the carriage M, as, that at the proper time,it m'ay be advanced or brought up and made to separate the clothes pinfrom' the stick from which it is being made. The carriage M, issupported and made to move back and forth on ways, or horizontal railsN, N, extending across and on the carriage' G, herein before described.The carriage M, l denominate t-he cutter carriage.

Directly in front of the cutters for forming the head of the pin, isvthe bell mouth orifice O, and cutter P, which are supported on and bythe post K. The bell mouth orifice O, is for recieving, guiding andsupporting the advancing end of the stick, previous to its being turneddown or operated upon by the cutters Z, m, 0, and after it has beenreduced to a cylindrical shape by the cutter P, which is so arranged andmade as to perform this operation, or reduce the -wood to the propercylindrical shape to be further shaped by the other cutters.

The mechanism which operates the two carriages Gr, and M, may be thusexplained. Q is the driving shaft, which extends across the carriage G,is supported and turns in bearings R, R, (atlixed to the carriage) andhas a turning crank S, appliedyto one end of it. A circular disk orplate T, is fastened on the opposite end of the shaft Q, and has a smallfriction roller V, attached to its outer side as seen in Fig. `3. Thisfriction roller operates in connect-ion with a series of pins V, V2, V3,V4, being each of the same length, and placed at equal distancesasunder, as seen in Fig. 3. On revolving the shaft Q, in the properdirection, the rack of pins, and the friction roller by their actiontogether, will cause the carriage G, to be moved toward or away from themandrel as occasion may require.

On the shaft Q, is a circular plate p, having a cam g, aiiiXed to itsside as seen in Fig. 1. The said cam g operates in connection with oneend of a lever 7, which turns horizontally on a fulcrum s, extending upfrom the 4rail bar N', of the carriage G. The other end of the saidlever r, is connected with the frame M, by means of a connecting link t,jointed to the frame and lever. During each revolution of the shaft Qthe cam g, is made to turn the lever on its fulcrum in such manner as tomove the carriage M, on its ways, and so as to draw the cutters Z, m,and o', against the stick while it is in revolution. As soon as thelever mounts up the cam, and by its upper or most projecting part, aweight, u, depending from a cord fu, (attached to the carriage M, andpassing over a pulley w) falls and retracts or drags back the carriageM, and cutters Z, m, 0.

The center rod D, has a cord x, afixed to its rear end. This cord iscarried a short distance toward the pointed end of the rods and thenceover a pulley y, and has a weight z, hung to it, the object of theweight and cord being to force the center rod forward against the stickimmediately after each clothes pin is severed from it. A weight a isalso hung to the rear end of the pattern lever, and fo-r the purpose ofkeeping it down upon the bottom of the opening of the fork L.

A stick of wood being affixed by one end to the mandrel has its otherend introduced into the bell mouth O, and against the reducing cutter P.This being done the Inandrel is put in revolution, and the crank S,

is turned so as to cause the carriage G, to

advance toward the mandrel. The stick will pass through the bell mouthor orifice O, and its end will be carried in Contact with the pointedend of the center rod D, and will next be met by the cutter eZ, andreduced by it or cut down for the required distance, to the shaperequired for the body part e, f of the clothes pin; the vertical falland rise of the cutter being produced by the movements of the patternlever, which are effected by the longitudinal retrogradation ofthecenter rod D, and the consequent movement of its fork against thecurved part of the pattern lever. As soon as the cutter d, has performedits oilice the cutters Z, m, o, are

brought up to the stick, and form the head of the pin, and separate thepin from the stick. The carriage G, being made to continue its forwardmovement, another pin may be made in a similar way, and so on until thewhole stick has been cut up.

What I claim, as my invention, is-

The rotary mandrel, the cutter for reducing the stick to a cylindricalshape, the cutter for forming the body of the pin, the cutter, orcutters, for forming the head, the center rod D, its fork and patternlever, the

`whole being applied to carriages, and made to operate togethersubstantially in manner and for the purpose as above specified.

In testimony whereof, I have hereto set my signature this twenty firstday of February A. D. 1849.
